If snow conditions don't improve the backup plan is to set lanterns on part of the trail and have it lit for walking.  Fires will be blazing, snacks will be out and people will be there to socialize.

There is over 5km of Lantern Lit trails with three cabins to warm and
refresh  yourself.  This is a very unique experience for
skiers old and new. The Lanterns are lit at dusk with many families
bringing hot dogs to roast over one of the fires, for
dinner. Enjoy this photos of the 2009 Night of
Lights.
